Amy Winehouse has further worried friends and family members after she was spotted wandering around the street in the early hours of Sunday morning wearing just a bra and jeans.

Amy had spent the evening partying at a friend’s house in East London but at 5.40am on Sunday morning, emerged from the house by herself.

An onlooker reports: “Amy came out and started stumbling around. She came out of the house, walked down the drive and wandered around on the pavement for a bit.”

“She looked upset and agitated but there was no obvious reason for her to have come outside. It was weird.”

“It was freezing and she had no shoes and just a red bra. She was mumbling something incomprehensible. It wasn’t the behaviour of someone in the right state of mind.”

A spokesperson for the singer added: “Amy had been asleep and heard a noise. She went outside to investigate. She didn’t realise the time.”

In related news, a source close the star has claimed her teeth are falling out as a result of her drug use and general state of ill-health at the moment.

The source told the Daily Mail: “Amy is very upset about her teeth because they have literally been falling out.”

“She has one missing from the front of her mouth, and another one at the back which is less visible.”

“Her mouth is full of holes and she is desperately worried she is going to lose more. She has actually pulled a tooth out herself, which is absolutely disgusting.”

“She picks at them all the time. Her gums are always red and sore as a result of it and some of the teeth are loosening.”

Last week, Amy cancelled the remaining dates on her UK tour on the instructions of her doctor, after she was deemed to be suffering from stress and exhaustion.
